I. The Crisis of Truth in Modern Culture
We live in a “post-truth” era. Oxford Dictionaries famously declared post-truth its Word of the Year in 2016, defining it as situations where objective facts are less influential in shaping public opinion than appeals to emotion and personal belief. In other words, feelings often trump facts in today’s public square.
The modern mantra is “live your truth.” Society increasingly speaks of “your truth” versus “the truth,” implying that truth is personal and subjective. As one young adult put it: “I kind of feel like there isn’t one truth. Of course there’s facts… When it comes to perspective on things? There’s a lot of wiggle room.” This captures the cultural shift from truth as something we discover to truth as something we construct based on personal experience.
We see the paradox everywhere. We demand objectivity in science and factual matters — no one says “gravity is just my truth.” Yet we insist on subjectivity in morality, identity, and meaning. This inconsistency points to an uncomfortable reality: if some truth is objective, perhaps not all truth is up for grabs.
Christianity cuts through the confusion with a radical assertion: Truth is not invented, not voted on, not merely felt — truth is revealed. It exists independent of us. And in fact, Truth has a name.
II. John 14:6 — Truth Is Not a Concept, but a Person
“I am the way, and the truth, and the life. No one comes to the Father except through me.”John 14:6 (NASB1995)
A. The Greek Grammar That Changes Everything
In John 14:6, Jesus makes a staggering claim. In Greek, the phrase is ἐγώ εἰμι (egō eimi) — an emphatic “I AM,” echoing the divine name of Exodus 3:14 and asserting exclusivity. Each predicate carries the definite article: “the way… the truth… the life” (hē hodos, hē alētheia, hē zōē in Greek). The grammar leaves no room for ambiguity. Jesus is not presenting Himself as a truth or one possible path among many, but the one-and-only Truth. The definite article signals a singular, absolute sense — truth in its totality is embodied in Him.
This is not mere moral guidance or opinion. It is an ontological claim about Jesus’ identity. By saying “I AM the Truth,” Christ identifies Himself with Truth itself, in person. No philosopher, prophet, or religious founder ever made such an audacious claim.
B. The Cultural Shock of Jesus’ Statement
Jesus’ Jewish and Greek contemporaries had their own expectations about “truth” — and His claim upended both.
- First-century Judaism: For the Jews, truth was found in the Torah. A rabbinic saying went, “Moses and his law are truth” and “there is no truth but the law.” No devout Jew would lightly call a person “the truth.”
- Greek philosophy: Greek thinkers sought truth in the concept of logos — the rational principle giving order and meaning to the universe. Crucially, this Greek logos was seen as an impersonal cosmic force or abstract principle, certainly not a human being.
- Jesus’ claim: Into this world, Jesus asserts truth is embodied in Him. He doesn’t just teach truth — He is truth. To the Jewish mind, He was saying the Torah finds its fulfillment in Him. To the Greek mind, John was saying the impersonal rational principle you talk about is actually a Person — and that Person is Christ.
This claim immediately excludes relativism by definition. If Jesus is the Truth for all people, then truth isn’t a choose-your-own adventure. As the apostle Peter boldly declared, “there is no other name” by which we can be saved (Acts 4:12) — an inherently exclusive, absolute claim.
III. John 1:1–14 — The Word Is Truth, and the Word Became Flesh
“In the beginning was the Word… and the Word became flesh, full of grace and truth.”John 1:1, 14 (NASB1995)
1. Logos: Truth Before Creation
John opens his Gospel: “In the beginning was the Word (Logos), and the Word was with God, and the Word was God.” By choosing logos, John deliberately invokes a term loaded with meaning for his audience. In Greek thought, λόγος could mean reason, logic, or the organizing principle of the cosmos. John reclaims this term with startling new significance: Logos is not an abstract idea or impersonal force. Logos is a Person. The eternal Truth who “was with God” and “was God” from the beginning entered into our world. This means:
- Truth pre-exists creation. Before the universe existed, Truth existed — in the person of God. Truth is eternal, not a byproduct of evolving human culture or opinion.
- Truth is the source of reality. All things were made through the Logos (John 1:3). The material world is entirely relative to the Truth of God’s Word. Reality conforms to God, not the other way around.
- Truth became tangible. Rather than leaving us to philosophize our way to truth, God revealed it concretely. Truth took on a face, a voice, a human life we could observe.
2. Truth as Eternal and Unchanging
If the Word (Truth) was “in the beginning” with God, and is God, then Truth’s nature is tied to God’s nature. Scripture emphasizes that God is unchanging (Malachi 3:6, Hebrews 13:8). Therefore, truth is unchanging. It is not subject to the whims of societal change or personal preference.
This is a crucial point in our post-truth age: Truth is not evolving with each generation’s opinions. Yes, our understanding of truth can grow, but truth itself — especially moral and spiritual truth — remains firmly fixed in God’s character. Jesus prayed, “Your word is truth” (John 17:17). As Jesus Himself declared, “Heaven and earth will pass away, but My words will never pass away” (Matthew 24:35).
3. Grace and Truth Are Inseparable
When the Word became flesh, John 1:14 testifies that He came “full of grace and truth.” Far from being a cold, harsh absolutism, the truth of Christ is wrapped in grace and love. In Jesus, we see compassion and truth united perfectly. The Gospel never pits love against truth — it presents truth spoken in love (Ephesians 4:15).
As pastor Warren Wiersbe put it, “Truth without love is brutality, and love without truth is hypocrisy.” Jesus could say to the woman caught in adultery, “Neither do I condemn you” and “go and sin no more” — extending grace and truth at once. Truth without grace wounds. Grace without truth deceives. But grace with truth heals.
IV. John 17:17 — Truth Is the Word of God
“Sanctify them by the truth; Your word is truth.”John 17:17 (NASB1995)
A. Jesus Defines Truth for Us
In His High Priestly Prayer, Jesus makes a remarkable equivalence: “Your word is truth.” Notice: He doesn’t say God’s Word contains truth, as if it were a mix of truth and error. He doesn’t say God’s Word becomes true when we believe it. He says it flat-out: God’s Word = truth. If Christ, who is the Truth, calls the Word of God “truth,” then the follower of Christ cannot treat God’s revelation as just one truth among many — it must be the measuring stick of truth.
Jesus routinely appealed to “It is written…” to settle matters. He even said, “Scripture cannot be broken” (John 10:35). For the early Christians, the Word of God was the final court of appeal for truth — an objective foundation, as opposed to the shifting sands of personal feelings or popular opinion.
B. Truth That Transforms
Jesus’ prayer links truth with sanctification. To sanctify means to make holy, to set apart for God. This tells us that truth is not merely informational — it is transformational. God’s truth has a purpose: to change us. Jesus told new believers, “If you abide in My word, you are truly my disciples, and you will know the truth, and the truth will set you free” (John 8:31–32). Note the sequence: continue in His Word → know the truth → be set free. Truth brings freedom from slavery to sin and falsehood, much like a sharp scalpel excising a cancer.
C. Truth Over Experience, Not Experience Over Truth
Modern culture often reverses the order: people start with their experience and feelings, and then determine what they will hold as “truth.” The biblical approach is the opposite — start with God’s truth and interpret your experiences in its light. Experiences and feelings are real, but they are not infallible. They can mislead.
A person might “feel” that God has abandoned them — that becomes their truth. But God’s Word objectively says, “I will never leave you nor forsake you” (Hebrews 13:5). Which truth should they live by? If experience is ultimate, they’ll despair. If God’s promise is ultimate, they’ll take hope despite their feelings. This is the loving aspect of absolute truth: it protects us from self-deception.
V. Truth as a Sword — Cutting Through Illusion
“For the word of God is living and powerful, and sharper than any two-edged sword… piercing to the division of soul and spirit… and discerning the thoughts and intents of the heart.”Hebrews 4:12 (NASB1995)
A. The Word as Surgical Blade
The Greek word for “sword” here is μάχαιρα (machaira) — a short sword or large knife, much like a Roman dagger, the kind of blade a surgeon might use. In modern terms, we might think of it as a scalpel. The imagery is precise: God’s Word cuts deeply and accurately. It separates what is of the soul and what is of the spirit, judging the thoughts and attitudes of the heart.
A two-edged blade cuts both ways — there is no blunt side. Likewise, truth cuts through all lies and pretenses. As one commentator notes, God’s Word “comforts the afflicted and afflicts the comfortable; it tears down and builds up; it convicts and converts.” Just as a surgeon’s scalpel cuts in order to heal, God’s Word sometimes cuts us in order to bring true healing.
B. Why Truth Often Feels “Offensive”
In our culture, telling someone a hard truth is often labeled as hurtful or offensive. But the discomfort we feel under the knife of truth is like the sting of a surgeon’s incision — it is pain with a purpose. The truth confronts our fleshly desires, our pride, and our false identities, shattering the lies we cling to about who we are apart from God.
Spurgeon put it well: “It kills nothing but that which ought to be killed… It quickens and gives new life to all that is of God.” In other words, truth hurts only to heal. “Faithful are the wounds of a friend,” says Proverbs 27:6 — and Truth is the best friend, though it wounds us in love.
VI. Old Testament Foundations — Truth Is God’s Nature
A. The Hebrew Concept of Truth — ‘Emet (אֱמֶת)
In the Old Testament, the chief Hebrew word for “truth” is ’emet. At its core, it means firmness, reliability, faithfulness, sureness. So Hebrew “truth” isn’t merely factual accuracy — it’s that which can be trusted fully. It has a relational quality. Truth is what you can stake your life on.
‘Emet is often paired with chesed (covenant love/mercy) in the Old Testament (Exodus 34:6, “abounding in lovingkindness and truth”). Together they convey God’s loyal love and faithful truth. It’s worth noting that ’emet is also translated “faithfulness” in many verses. Psalm 100:5 — “His truth endures to all generations” — can equally be rendered “His faithfulness endures to all generations.” In Hebrew thought, truth is what remains faithful and reliable over time. It’s not just a correct fact; it’s an enduring reality.
B. Truth Flows from God’s Character
God doesn’t just tell the truth — God is truth. “A God of faithfulness and without injustice; righteous and upright is He” (Deuteronomy 32:4). The prophets call God “El Emet” — God of Truth/Faithfulness (Psalm 31:5, Isaiah 65:16). Unlike the capricious pagan deities, the God of Israel was absolutely consistent and reliable. He cannot lie (Numbers 23:19). When He makes a covenant, He keeps it. When He speaks, it is wholly true.
This explains why absolute truth must exist: if there is an unchanging God who is true, then there are unchanging truths that flow from His character. God’s holiness, love, justice, and faithfulness define moral realities for the universe. Because God is just, justice is not a human invention. Because God is faithful, trust and honesty are not relative social constructs — they are reflections of God’s eternal character.
C. Torah as Truth — Revelation, Not Oppression
Sometimes people today think of God’s law as something negative or oppressive. But the Old Testament saints saw it very differently — they celebrated the Law because it was truth from God. “Your Torah is truth,” exclaims Psalm 119:142. The Torah was instruction from the Designer about how life works best — a pathway to human flourishing, not a shackle. When people followed God’s truth, it brought societal shalom (peace/wholeness). When Israel abandoned truth and “everyone did what was right in their own eyes,” trouble followed.
There is a straight line from the Old Testament to the New on truth: God’s truth is a solid rock in a world of shifting sands. It was true for Abraham, Moses, and David. It remains true for us today.
VII. Relativism vs. Absolute Truth — A Worldview Clash
A. The Self-Contradiction of Relativism
Relativism is the belief that truth is not universal or objective but relative to each person or culture — “you have your truth, I have mine.” Such claims may sound liberating at first, but they collapse under their own logic. Consider the assertion: “There is no absolute truth.” Is that statement absolutely true? If the relativist says yes, he’s just contradicted himself — he’s smuggled in one absolute truth. If he says no, the statement carries no persuasive force — it’s just personal opinion with no claim on others. Either way, the relativist’s central creed self-destructs.
As Christian philosopher Francis Beckwith quipped: “Relativists all have one absolute: Thou shalt not disagree with me.”
B. Why Culture Rejects Absolute Truth
If relativism is so illogical, why is it popular? There are a few key reasons:
- Accountability: The moment we acknowledge an absolute moral truth, we are accountable to it. In a relativistic framework, no one can authoritatively tell me I’m wrong — I become, in effect, a law unto myself. Absolute truth, by contrast, implies authority beyond me. Ultimately, it implies God’s authority — which is why a culture that prizes individual autonomy bristles at the phrase “Divine Law.”
- Desire for autonomy: Modern Western culture places a premium on personal freedom defined as the absence of constraints. In this view, truth claims are seen as power plays — someone else’s attempt to impose their reality. Tim Keller summarizes the cultural sentiment: “People believe absolute truth is the enemy of freedom… everyone should be free to determine their own truth.”
- Moral complexity and pluralism: We live in a pluralistic society with many worldviews. Embracing relativism seems polite — “you have your truth, I have mine, let’s just get along.” It’s a peacekeeping strategy that only works superficially.
C. Christianity’s Bold Claim
Into this relativistic climate, Christianity makes a daring and politically incorrect claim: Absolute truth not only exists — it can be known, and it will set you free. Jesus said, “You shall know the truth, and the truth shall make you free” (John 8:32). Far from undermining freedom, knowing God’s truth is the gateway to true freedom — freedom from sin, from error, from the bondage of constantly shifting values.
Christianity unabashedly teaches that truth is not oppressive — it’s redemptive. It’s falsehood that enslaves. Moreover, Christianity centers all truth in a Person — Jesus Christ — who loves us and gave Himself for us. That is not the profile of an oppressor but a Savior. As apologist Ravi Zacharias put it: “Truth that is not undergirded by love makes the truth obnoxious and the possessor of it repulsive.” We present the truth with love and let its liberating power do the work.
To summarize the clash: Relativism offers a throne for the Self, but no foundation for society or salvation. Christianity offers a throne for Christ as Truth, which in turn brings coherence, salvation, and true freedom to the self.
VIII. Why This Matters Today
Without absolute truth:
- Justice becomes arbitrary. If there is no objective moral truth, concepts of right and wrong shift with popular opinion. Laws become based on power or preference, not enduring principle. True justice cannot survive in a relativistic framework, because justice assumes a standard of rightness beyond personal feelings.
- Identity becomes unstable. People are told to “define your own truth” about who you are — the result is confusion and fragmentation. Depression and anxiety soar when individuals are tasked to self-create meaning and identity (an impossible burden). In contrast, knowing we are created in God’s image, fallen in sin, yet redeemable and loved in Christ gives a stable identity anchored in truth.
- Meaning and purpose dissolve. Without objective truth, we’re left with nihilism or endless subjective “projects” we invent to distract ourselves. As Solomon learned in Ecclesiastes, trying to invent your own meaning “under the sun” apart from God is chasing the wind.
With absolute truth:
- Identity is anchored. When you understand truths like “God created me with a purpose” (Psalm 139) or “In Christ, I am a child of God” (Galatians 3:26), there is a solid identity that isn’t shattered by life’s storms. The truth of who God is and who you are in relation to Him provides a rock to stand on.
- Morality is coherent and consistent. An absolute moral truth gives you a compass. You aren’t at the mercy of whatever is trending. This coherence breeds integrity and provides common ground for society — a shared truth to appeal to when resolving disputes or crafting laws.
- Hope is grounded. Absolute truth includes absolute promises from God. The promise of eternal life through Christ is not a “maybe” — it’s a sure truth if the resurrection is true. As Hebrews 6:19 says, “We have this hope as an anchor for the soul, firm and secure.” In times of crisis, knowing there is real truth and justice in God’s hands is incredibly stabilizing.
C.S. Lewis warned of the dangers of abandoning objective values. In The Abolition of Man, he wrote that without a return to belief in objective truth and values, we risk losing our humanity: “Unless we return to the crude and nursery-like belief in objective values, we perish.” Our moment in history — with fake news, misinformation, and ideological polarization — highlights the chaos that ensues when truth is devalued. The stand for absolute truth is not about being obstinate or old-fashioned. It is about preserving the possibility of sanity, trust, and meaning in human life.
IX. Closing Thesis
Truth is not something we invent or create.
Truth is Someone we encounter.
And His name is Jesus Christ.
In an age of confusion, Christ stands unique and unchanging — “the same yesterday, today, and forever” (Hebrews 13:8). He is the answer to the post-truth moment — not a concept to debate, but a Person to know. And in knowing Him, we find not just the truth about the world, but the truth about ourselves.
